TimeseriesOptions is impossible to use

[fuwaneko]

I was trying to create timeseries collection via driver and found that it's not possible since TimeseriesOptions is marked as non-exhaustive so there's no way to instantiate that structure outside mongodb crate. Please, either add derive(Default) or create a function to instantiate TimeseriesOptions struct.

Hi @fuwaneko, thank you for filing this issue! Our options derive the TypedBuilder trait so that users can use the builder pattern to constructs options, but it looks like that was unintentionally omitted from TimeseriesOptions. I created #557 to fix this.

@fuwaneko The fix for this has been merged and will be included in the next release. Thanks again for filing this issue!
